Description

La présente invention concerne le domaine des dispositifs de connexion.The present invention relates to the field of connection devices.

La présente invention concerne plus préci­sément un dispositif de connexion pour un ensemble de commutation porté par la colonne de direction d'un véhi­cule automobile.The present invention relates more precisely to a connection device for a switching assembly carried by the steering column of a motor vehicle.

Un premier but de l'invention est de pro­poser un dispositif de connexion adapté à un ensemble de commutation porté par une colonne de direction réglable en hauteur par pivotement.A first object of the invention is to provide a connection device suitable for a switching assembly carried by a steering column adjustable in height by pivoting.

Un autre but de la présente invention est de proposer un dispositif de connexion apte à permettre un montage automatisé de l'ensemble de commutation associé.Another object of the present invention is to provide a connection device capable of allowing automated mounting of the associated switching assembly.

Ces différents buts sont atteints dans le cadre de la présente invention grâce à un dispositif de connexion comprenant de façon classique en soi deux éléments de connexion liés respectivement à l'ensemble de commutation et à une platine fixe et destinés à venir en contact mutuel, caractérisé par le fait que l'un des éléments de connexion comprend au moins une piste élec­triquement conductrice allongée, rectiligne, apte à rester en contact avec l'autre élément de connexion lors de déplacements de l'ensemble de commutation dans une direction générale parallèle à la direction de ladite piste conductrice.These various aims are achieved within the framework of the present invention by means of a connection device conventionally comprising per se two connection elements linked respectively to the switching assembly and to a fixed plate and intended to come into mutual contact, characterized by the fact that one of the connection elements comprises at least one elongated electrically conductive track, rectilinear, capable of remaining in contact with the other connection element during movements of the switching assembly in a general direction parallel to the direction of said conductive track.

La structure proposée dans le cadre de la présente invention permet de maintenir un contact entre les deux éléments de connexion quelle que soit la posi­tion de la colonne de direction.The structure proposed in the context of the present invention makes it possible to maintain contact between the two connection elements regardless of the position of the steering column.

De plus, l'utilisation d'un élément de connexion qui comporte une piste conductrice allongée facilite largement l'assemblage automatisé d'un commu­tateur prééquipant la colonne de direction.In addition, the use of a connection element which comprises an elongated conductive track greatly facilitates the automated assembly of a switch pre-equipping the steering column.

Selon une caractéristique avantageuse de l'invention les deux éléments de connexion sont pourvus de moyens de serrage aptes à renforcer le contact mutuel entre les deux éléments ; ces moyens de serrage sont de préférence reliés aux moyens de blocage associés à la colonne de direction, pour être actionnés simultanément à ceux-ci.According to an advantageous characteristic of the invention, the two connection elements are provided with clamping means capable of strengthening the mutual contact between the two elements; these clamping means are preferably connected to the blocking means associated with the steering column, to be actuated simultaneously with these.

Selon un mode de réalisation considéré actuellement comme préférentiel, l'un des éléments de connexion comprend un corps support en matériau souple au moins légèrement compressible pourvu d'une pluralité de rainures rectilignes parallèles qui logent chacune un organe de connexion allongé rectiligne. Lorsque les moyens de serrage compriment le corps support, un contact intime est garanti entre les deux éléments de connexion.According to an embodiment currently considered preferential, one of the connection elements comprises a support body of flexible material at least slightly compressible provided with a plurality of parallel rectilinear grooves which each house a rectilinear elongate connection member. When the clamping means compress the support body, intimate contact is guaranteed between the two connection elements.

On aperçoit sur les figures annexées une colonne de direction 10 portant un volant 12 et suscepti­ble de pivotement autour d'un axe horizontal 14. Le dé­battement angulaire de la colonne de direction 10 autour de l'axe 14 est illustré schématiquement sous la référence α.We see in the accompanying figures a steering column 10 carrying a steering wheel 12 and capable of pivoting about a horizontal axis 14. The angular movement of the steering column 10 around the axis 14 is illustrated schematically under the reference α.

La colonne 10 est équipée de moyens de blocage aptes à immobiliser celle-ci dans une position quelcon­que choisie, lors de son pivotement autour de l'axe 14.The column 10 is equipped with blocking means capable of immobilizing the latter in any chosen position, during its pivoting around the axis 14.

Selon le mode de réalisation illustré sur les figures annexées, mais non limitatif, les moyens de blocage comprennent un étrier 18 fixé sur la colonne de direction 10 et deux flasques 22, 24 solidaires du châs­sis du véhicule. Les faces latérales de l'étrier 18 et les deux flasques 22, 24 s'étendent transversalement à l'axe 14 de pivotement de la colonne 10. Les flasques 22, 24 sont susceptibles de pincer l'étrier 18 grâce à un système fileté 20.According to the embodiment illustrated in the appended figures, but not limiting, the locking means comprise a bracket 18 fixed on the steering column 10 and two flanges 22, 24 secured to the chassis of the vehicle. The lateral faces of the stirrup 18 and the two flanges 22, 24 extend transversely to the pivot axis 14 of the column 10. The flanges 22, 24 are capable of pinching the stirrup 18 thanks to a threaded system 20 .

Le système fileté 20 comprend une tige filetée 26 traversant l'étrier 18 et les deux flasques 22, 24, et qui coopère avec un écrou de serrage 28.The threaded system 20 comprises a threaded rod 26 passing through the stirrup 18 and the two flanges 22, 24, and which cooperates with a tightening nut 28.

On aperçoit également sur les figures annexées, une platine fixe 30 solidaire du châssis du véhicule et une coquille d'habillage 16 solidaire de la colonne de direction.We also see in the accompanying figures, a fixed plate 30 secured to the vehicle chassis and a covering shell 16 secured to the steering column.

La colonne de direction 10 porte un ensem­ble de commutation 40 schématiquement illustré sur la figure 1. De nombreux ensembles de commutation ont déjà été proposés. Pour cette raison la structure de l'ensem­ble de commutation 40 ne sera pas décrite plus en détail par la suite.The steering column 10 carries a switching assembly 40 schematically illustrated in FIG. 1. Many switching assemblies have already been proposed. For this reason, the structure of the switching assembly 40 will not be described in more detail below.

Dans le cadre de la présente invention, il est prévu un dispositif de connexion 50 qui comprend deux éléments de connexion 60, 70.In the context of the present invention, there is provided a connection device 50 which comprises two connection elements 60, 70.

Les éléments de connexion 60, 70 sont liés respectivement à l'ensemble de commutation 40 et à la platine 30. Ces éléments de connexion sont destinés à venir en contact mutuel, pour relier l'ensemble de commutation 40 aux divers accessoires du véhicule, par exemple avertisseur sonore, ou moyen de signalisation lumineuse.The connection elements 60, 70 are respectively linked to the switching assembly 40 and to the plate 30. These connection elements are intended to come into mutual contact, to connect the switching assembly 40 to the various accessories of the vehicle, by example of audible warning, or means of light signaling.

Selon l'illustration donnée sur la figure annexée, l'élément de connexion 60 lié à l'ensemble de commutation 40 constitue un élément de connexion mâle tandis que l'élément de connexion 70 lié à la platine 30 constitue un élément de connexion femelle.According to the illustration given in the appended figure, the connection element 60 linked to the switching assembly 40 constitutes a male connection element while the connection element 70 linked to the plate 30 constitutes a female connection element.

Plus précisément, de préférence, chacun des éléments de connexion comprend une pluralité de voies.More specifically, preferably, each of the connection elements comprises a plurality of channels.

Pour cette raison, l'élément de connexion 60 lié à l'ensemble de commutation 40 comprend une plura­lité de broches parallèles.For this reason, the connection element 60 linked to the switching assembly 40 comprises a plurality of parallel pins.

L'élément de connexion 70 lié à la platine 30 comprend un corps support 72 en matériau souple au moins légèrement compressible. Le corps 72 est pourvu d'une pluralité de rainures rectilignes parallèles 74, ces rainu­ res 74 s'étendent transversalement à l'axe 14 de pivote­ment de la colonne 10. Chacune des rainures 74 loge un organe de connexion allongé rectiligne 80.The connection element 70 linked to the plate 30 comprises a support body 72 of flexible material at least slightly compressible. The body 72 is provided with a plurality of parallel rectilinear grooves 74, these grooves res 74 extend transversely to the pivot axis 14 of the column 10. Each of the grooves 74 houses a straight elongated connection member 80.

Comme illustré sur la figure 4, de préfé­rence, chaque organe de connexion 80 comprend deux la­melles 82, 84, généralement parallèles, reliées par leur base et formant des pinces de connexion. Les organes de connexion 80 sont fixés par leur base 86 sur le corps support 72. La base 86 des organes de connexion 80 peut prendre de nombreuses formes à cet effet. Pour cette raison la forme des organes de connexion 80 ne sera pas décrite plus en détail par la suite.As illustrated in FIG. 4, preferably, each connection member 80 comprises two strips 82, 84, generally parallel, connected by their base and forming connection clips. The connection members 80 are fixed by their base 86 to the support body 72. The base 86 of the connection members 80 can take many forms for this purpose. For this reason, the shape of the connection members 80 will not be described in more detail below.

Les lamelles 82, 84 s'étendent transversale­ment à l'axe 14 de pivotement de la colonne de direction 10, contre les parois internes des rainures 74.The lamellae 82, 84 extend transversely to the pivot axis 14 of the steering column 10, against the internal walls of the grooves 74.

Les broches appartenant à l'élément de con­nexion 60 sont destinées à pénétrer dans l'espace 88 com­pris entre les deux lamelles 82, 84 d'un même organe. Pour faciliter l'engagement des broches 62 de l'élément de con­nexion 60 dans l'espace 88, de préférence comme illustré sur la figure 4, les bords libres 83, 85 des lamelles 82, 84, sont divergentes. De plus, pour garantir que les bro­ches 62 pénètrent dans l'espace 88 et donc éviter que les broches puissent pénétrer entre l'une des lamelles 82, 84 et la paroi de la rainure 74 associée, le corps 72 est pourvu, entre les rainures 74 et du côté de l'engagement des broches, de structures évasées 76 qui recouvrent le bord libre 83, 85 des lamelles 82, 84 (voir figure 4).The pins belonging to the connection element 60 are intended to penetrate into the space 88 between the two strips 82, 84 of the same member. To facilitate the engagement of the pins 62 of the connection element 60 in the space 88, preferably as illustrated in FIG. 4, the free edges 83, 85 of the strips 82, 84, are divergent. In addition, to ensure that the pins 62 penetrate into the space 88 and therefore prevent the pins from entering between one of the lamellae 82, 84 and the wall of the associated groove 74, the body 72 is provided, between the grooves 74 and on the engagement side of the pins, flared structures 76 which cover the free edge 83, 85 of the strips 82, 84 (see FIG. 4).

On notera de plus que pour garantir un bon contact entre les broches 62 et les organes de connexion 80 ceux-ci sont pourvus de préférence, sur la surface interne en regard des lamelles 82, 84 et au voisinage des bords libres 83, 85, par déformation, d'un resserrement 87, 89 destiné à serrer chaque broche 62 associée.It will also be noted that to guarantee good contact between the pins 62 and the connection members 80 these are preferably provided, on the internal surface facing the lamellae 82, 84 and in the vicinity of the free edges 83, 85, by deformation, a constriction 87, 89 intended to clamp each associated pin 62.

On va maintenant décrire la structure de moyens de serrage 100 destinés à renforcer le contact mutuel entre les éléments de connexion 60, 70 et plus précisément entre les broches 62 et les organes de con­nexion 80 respectivement associés.We will now describe the structure of clamping means 100 intended to reinforce mutual contact between the connection elements 60, 70 and more precisely between the pins 62 and the connection members 80 respectively associated.

Comme illustré sur les figures le corps 72 de l'élément 70 repose contre la surface externe de l'un des flasques 22, 24 précités ou un élément lié à celui-ci.As illustrated in the figures, the body 72 of the element 70 rests against the external surface of one of the abovementioned flanges 22, 24 or an element linked to the latter.

Les moyens de serrage 100 comprennent un équipage 102 et un ressort 104. Le ressort 104 est dispo­sé entre le corps 72 et l'équipage mobile 102. Lorsque cela est requis l'équipage 102 est déplacé en rappro­chement du corps 72 pour solliciter et comprimer celui-­ci afin de resserrer les organes de connexion 80 sur une broche 62 associée. Le ressort 104 intercalé entre l'équi­page 102 et le corps 72 limite l'effort exercé sur le corps 62 et les organes de connexion.The clamping means 100 comprise an assembly 102 and a spring 104. The spring 104 is disposed between the body 72 and the movable assembly 102. When required, the assembly 102 is moved closer to the body 72 in order to stress and compress that here in order to tighten the connection members 80 on an associated pin 62. The spring 104 interposed between the assembly 102 and the body 72 limits the force exerted on the body 62 and the connection members.

De préférence, une entretoise 106 est intercalée entre le ressort 104 et le corps 72.Preferably, a spacer 106 is interposed between the spring 104 and the body 72.

L'équipage mobile 102 peut être actionné par de nombreux moyens.The moving element 102 can be actuated by numerous means.

Selon le mode de réalisation préféren­tiel illustré sur les figures annexées, l'équipage mobile 102 est actionné par des moyens reliés aux moyens de blocage de la colonne de direction pour être actionnés simultanément à ceux-ci.According to the preferred embodiment illustrated in the appended figures, the mobile assembly 102 is actuated by means connected to the locking means of the steering column so as to be actuated simultaneously with these.

Plus précisément encore, selon la réalisa­tion donnée sur les figures annexées, l'écrou 28 précité en prise avec la tige filetée 26 sert de pré-réglage, le serrage proprement dit après positionnement approprié de la colonne de direction 10 étant réalisé à l'aide d'une came 29 montée à pivotement sur la tige 26 autour d'un axe 27 excentré. La came 29 est commandée à déplacement autour de l'axe 27 par un levier 25.More precisely still, according to the embodiment given in the appended figures, the aforementioned nut 28 engaged with the threaded rod 26 serves as a pre-adjustment, the actual tightening after appropriate positioning of the steering column 10 being carried out using a cam 29 pivotally mounted on the rod 26 about an eccentric axis 27. The cam 29 is controlled to move around the axis 27 by a lever 25.

Les moyens assurant le déplacement de l'équi­page mobile 102 comprennent également une came excentrée 108. De préférence, la came 108 est reliée à la came de blocage 29 précitée par l'intermédiaire d'une bielle 110. Ainsi, les moyens de serrage agissant sur l'élément de connexion 70 sont commandés simultanément aux moyens de blocage 20.The means ensuring the movement of the mobile assembly 102 also comprise an eccentric cam 108. Preferably, the cam 108 is connected to the abovementioned locking cam 29 by means of a connecting rod 110. Thus, the clamping means acting on the connection element 70 are controlled simultaneously to the locking means 20.

Le fonctionnement du dispositif qui vient d'être décrit est le suivant.The operation of the device which has just been described is as follows.

Lorque la came 29 est placée en position desserrée, la colonne de direction 10 peut être déplacée librement à pivotement autour de l'axe 14 en vue d'un réglage en hauteur. Simultanément, la came 108 associée à l'équipage mobile 102 est placée en position desser­rée. De ce fait, les broches 62 peuvent se déplacer libre­ment dans les organes de connexion 80 lors du réglage de la colonne de direction 10. Lorsque la came 29 est déplacée en position de serrage, la colonne de direction 10 est immobilisée fermement. Simultanément au déplacement de la came 29, la came 108 est déplacée en position de serrage pour solliciter l'équipage 102 contre le corps 72 afin de comprimer celui-ci. Les organes de connexion 80 se resserrent alors sur les broches 62 pour garantir un contact intime entre les deux éléments de connexion 60 et 70.When the cam 29 is placed in the released position, the steering column 10 can be moved freely by pivoting about the axis 14 for a height adjustment. Simultaneously, the cam 108 associated with the moving element 102 is placed in the released position. Therefore, the pins 62 can move freely in the connection members 80 when adjusting the steering column 10. When the cam 29 is moved to the clamping position, the steering column 10 is immobilized firmly. Simultaneously with the movement of the cam 29, the cam 108 is moved to the clamping position to urge the crew 102 against the body 72 in order to compress the latter. The connection members 80 are then tightened on pins 62 to guarantee intimate contact between the two connection elements 60 and 70.

Grâce à la forme allongée des organes de connexion 80, transversalement à l'axe de pivotement 14, les broches 62 et les organes de connexion 80 restent en contact permanent quelle que soit la position de la colon­ne de direction 10 autour de l'axe de pivotement 14.Thanks to the elongated shape of the connection members 80, transversely to the pivot axis 14, the pins 62 and the connection members 80 remain in permanent contact regardless of the position of the steering column 10 around the axis of pivot 14.

Bien entendu la présente invention n'est pas limitée au mode de réalisation particulier qui vient d'être décrit mais s'étend à toute variante conforme à son esprit.Of course the present invention is not limited to the particular embodiment which has just been described but extends to any variant in accordance with its spirit.

A titre d'exemple, comme illustré sur les figures 2 et 3 annexées, les éléments de connexion confor­mes à la présente invention peuvent être décomposés cha­cun en deux sous-ensembles, le cas échéant symétriques par rapport à la colonne de direction. Sur la figure 2, on a illustré sous les mêmes références numériques que précédemment,mais assorties d'un indice,un deuxième sous-­ensemble commandé par la même came excentrée 108.By way of example, as illustrated in FIGS. 2 and 3 appended, the connection elements according to the present invention can be broken down each into two sub-assemblies, where appropriate symmetrical with respect to the steering column. In FIG. 2, a second sub-assembly controlled by the same eccentric cam 108 has been illustrated under the same numerical references as above, but accompanied by an index.

De plus, selon le mode de réalisation précé­demment décrit, les pistes électriques allongées sont ménagées sur l'élément de connexion femelle. Le cas échéant, les pistes conductrices allongées pourraient être ménagées sur l'élément de connexion mâle.In addition, according to the embodiment described above, the elongated electrical tracks are provided on the female connection element. If necessary, the elongated conductive tracks could be provided on the male connection element.

De même la position des éléments de conne­xion peut être inversée en ce sens que l'élément de con­nexion pourvu des pistes conductrices allongées pourrait être rendu solidaire de la colonne de direction 10 elle-­même.Likewise the position of the connection elements can be reversed in the sense that the connection element provided with elongated conductive tracks could be made integral with the steering column 10 itself.

Par ailleurs, la structure des moyens aptes à solliciter le serrage des organes de connexion 80 sur les broches 62 peut faire l'objet de nombreuses variantes de réalisation. A titre d'exemple on a illus­tré sur les figures 2 et 3 annexées deux exemples de réalisation de came 108 reliée à la came 29 par l'inter­médiaire d'une bielle 100.Furthermore, the structure of the means capable of requesting the tightening of the connection members 80 on the pins 62 can be the subject of numerous alternative embodiments. By way of example, there are illustrated in FIGS. 2 and 3 annexed two exemplary embodiments of a cam 108 connected to the cam 29 by means of a connecting rod 100.
